Review: 音が静かで 価格が安くて信頼性が高い - 到着予定日より早く届けてくださり ありがとうございます。 ファンの音が驚くほど小さくて、本当に動いているか不安になるぐらいで 驚きました。 とても、品質が良くて、5060RTXのモバイルGPU をeGPUとして運用することが出来ました。 持ち運べるGPUができあがりました。 一つ、感じた事は、うっすらと半導体が焼けた臭いがしたことです。 何日間か使用していて 薄れたので 最初の時だけかもしれません。
Review: The Teton (outdoor gear) of small form factor psu's - I really liked my 350-watt PSU (I have two of them in my backup NAS systems for RAID arrays running on the main NAS), but I think I overloaded one and burned it out. Technically, it still works, but it smells awful, so I contacted support. Their response was amazing—they sent me a new one right away. The support from this company is top-notch, and their products are affordable while performing their job well. Since I likely overloaded my 350-watt unit, I decided to upgrade to the 400-watt model to better handle my OpenMediaVault NAS server. My setup includes: - **CPU**: Intel i7-4770 - **RAM**: 16GB - **Networking**: 10Gb SFP+ NIC - **Storage**: 8× 12TB HDDs + 2× 220GB SSDs - **Cooling**: Noctua fans for both the case and CPU - **Motherboard**: A random Shenzhen Machinist board for Intel 1150 socket Since switching to the 400-watt PSU, it has been flawless. It hit the ground running and has powered my system 24/7 without a single issue. I run RAID arrays, virtual machines, and containers, and it's always connected to a UPS. I highly recommend this company and their products—I’d consider them the **Teton** of small-form-factor PSUs. Apevia did a great job with this product, and their support is outstanding. I especially love the **modular design**, which keeps my NAS’s internal cabling much cleaner. The PSU fan is **quiet**—I don’t even hear it. My Noctua fans (2× 80mm for the case and 1× 90mm for the CPU) are louder. Honestly, I wouldn’t bother replacing the PSU fan despite what some content creators suggest—the gains are almost nonexistent. If you’re considering this PSU, **go for it!** It’s an excellent value, and the company stands behind their products.

### ⭐⭐⭐⭐⭐ Works very well and quiet

I used this in a media-centre PC and it's efficient and quiet. I did initially have a problem with one of the power cables but I contacted support and they sent me a new cable within 1 week.
